The Devil wheels are designed for high-level roller skating, and to adapt your skating to many different surfaces, particularly very slippery ones, without compromising on speed and roll. • Given their characteristics, these wheels have been equipped with a rigid hub that allows them to roll extremely well, with incurring the typical flattening that is expected with very soft traditional wheels, or the slowdowns of polyurethane wheels.• The tread is produced by injection of a mix of thermoplastic polymer materials.• The rounded finish allows for use with little to no adjustment time.• It is possible to combine these wheels with the Professional wheels for a perfect balance between grip and smoothness.• Available in seven hardnesses (colors) and one diameter: 57mm.• Available in sets of 8 wheels (It is at the discretion of each reseller to sell units in smaller quantities). DIAMETER 57mm – HARDNESS 36 / 39 / 42 / 45 / 47 / 49 / 53 Shore DNOTE: in the transition from Magnum/Giotto to Devil, it is a good practice to consider a lowerhardness with respect to the previously used (ex: Magnum/Giotto 49 -> Devil 47)
